Double lap weld on .050 3003.
Planished in the Punishing Hammer, so .110" thick weld goes flat back to .050. Nice and smooth :)

and fast. No pinchy fingers. :)

annealing multiple metals - Cu, Ag, Au
Attachment 50268
hot bend - file. (Note: mistakes are great teachers: insufficient heat and excessive bend effort = crack.)

"Learn from others' mistakes - life is too short for you to make them all yourself."

I make these mistakes during class so students don't have to simply take my words without the demo. :):)

(I do the same thing on my instructional DVD's. I do not cut the camera off, fix the problem, and then resume "demonstrating." Nope, I believe to show the mistakes, and then show the results.)

Yeah skintcarter - all of the torches work, so anytime someone wants to try a such-and-such model, chances are it is somewhere in the torch drawer. :)
